Type SVT F-ST
In the laboratory and technology systems, bursting discs in the screw holder F-ST are used. In line with and on top of these requirements, STRIKO offers the alarm SVT F-ST for the downstream or parallel assembly.
Example of Design
|SVT F-ST||STRIKO VerfahrensTechnik F-ST|
The SVT F-ST alarm offers, in contrast to all other STRIKO alarms, the option of multiple usability. This means that the functionality of the alarm after displaying the opening of a bursting discs (in the F-ST holder) can be restored with only a few hand movements. Thus, the procurement of a new alarm is omitted which reduces your costs for operating the system.
Advantages in the application
- Alarm can be reused after displaying a malfunction
- Reliable detection thanks to innovative technology
- Quick identification of a malfunction
- Simple assembly
- Connection dimension of 1/4″ – 1″
- The alarm is a separate component and independent of the bursting disc
Note about ATEX
All burst indicators / leakage sensors from STRIKO according to the type of protection are rated “i” intrinsic safety – “simple electrical equipment” when connected to an intrinsically safe circuit. The requirements on “simple electrical equipment” are covered in section 5.7 of the standards EN 60079-11:2012 or IEC 60079-11 Ed. 6:2011-06 “Explosive atmospheres – Part 11: Equipment protection by intrinsic safety ‘i'”.
Simple electrical equipment, designed in accordance with the requirements of section 5.7 of the standards EN 60079-11:2012 or IEC 60079-11:2011 and section 16.4 of the standards EN 60079-14: 2014 or IEC 60079-14 Ed. 5: 2013-11 “Explosive atmospheres – Part 14: Electrical installations design, selection and erection” do not require certification; see section 4.4.2 of EN 60079-14: 2014 or IEC 60079-14 Ed. 5: 2013-11.
Such parts are also not governed by directive 94/9/EC since they do not feature any potential source of ignition. The designation of simple equipment can be made by any person/institution, including the manufacturer or installer, and made by freely selectable designation marking or coding preferred for the installation/plant.
